Remove all your fish from your tank by scooping them out of the water with your net. Place the fish in your backup aquarium, where they can safely reside while you clean the hard water deposits off your primary aquarium.

I am also having trouble finding fish that will not eat the plants but dont mind a high ph. so far i am going to get either 1 or 2 albino bristlenoses but beyond that i am not sure(my tank is 30 gallons 36" long). With my hard water and high ph i have thought about something from lake victoria but alot of those fish get to big and like to dig. i also have thought about tanganyika but i do not want shell dwellers and dont know what else i could get.

Aquarium Water That Is Too Hard - Petcha

One of the paradoxes in freshwater fishkeeping is thatwhile most fish naturally from soft water environments will thrive inhard water aquaria, the reverse is almost universally not true. Tetras,Barbs, Gouramis, catfish and Angelfish are allexamples of originally soft water fish that are routinely andsuccessfully kept in hard water community tanks. But Livebearers,Central American cichlids and Rift Valley cichlids almost never adaptto soft and acidic water conditions. In other words, if all you want isa mixed community tank, then hard and alkaline water will allow you tomix Platies, Neons and without problems.

As a rule, the popular South American tetrastend to tolerate rather than thrive in hard water. Some, like Neons,cardinals, and Glowlights, suffer somewhat, and their mortality inhard, alkaline water can be very high. Nonetheless, a few tetras doinhabit hard water streams and rivers, and these make excellent choicesfor the aquarist with a hard water aquarium. One of the best is thex-ray tetra, , a pretty, peaceful tetra thatadds colour and movement to any community of small fishes. It isn'ta fin-nipper, and so can be trusted with things like guppies, and isbig enough that it isn't at risk of being eaten by things likehalfbeaks or dwarf cichlids. Another fine choice for the community tankis the blind cave tetra, . Because this fishinhabits streams in limestone caves, it is perfectly adapted to hard,alkaline water. It is, of course, a wonderful oddball fish, and despitehaving no eyes it has an uncanny way of navigating and finding foodvery effectively; a splendid fish for the aquarist after somethingdifferent.
